  A longer-lived means of correcting colour vision deficiency is in the form of tinted spectacle or contact lenses. Typically, such lenses are worn monocularly, though they may be worn binocularly. Tinted lenses may also be used to provide a successive comparison by briefly viewing a visual scene through the lens. […] Clinical trials of bandpass filters have yielded generally disappointing results. Most studies imply that monocular long bandpass lenses have their main effect by either altering the colour confusions that those with colour vision deficiency make or by changing the relative brightness/lightness of different colours (ie by introducing luminance cues).

  Colour vision deficiency/colour blindness is not 100% blindness, rather it is a deficit in the perception of colour. Colour blindness is a hereditary disease that affects men more than women. […] Management of colour vision abnormalities can be corrected by using colour blind glasses. Tinted glass based on the type of colour blindness helps those CVD people to differentiate colour by filtering specific wavelengths through the proprietary optical material of the glasses. However, these glasses do not produce 100% normal colour vision nor cure colour blindness. […] Smartphone and computer apps or features also can be used in management of CVD.
